Color Calibration LCD Monitors for Video

F E A T U R E S
ColorEdge monitors deliver the picture consistency and color reproduction that studio professionals demand. Color
management features like hardware calibration and uniformity compensation are standard and select models offer 3D
look-up tables and preset color modes for working in common broadcast and digital cinema color spaces. ColorEdge even
boasts the unique CG232W, the world’s only video editing and master monitor. With ColorEdge you can be sure that the
colors you use during editing and post-production will be the same as those enjoyed by your audience.
Editing and Master Monitor
CG232W
This unique monitor offers multiple features that meet the various
demands of post-production, including color grading, image
evaluation and nonlinear editing for broadcasting. A button on the
monitor’s front bezel for switching between PC and SDI signals lets
studio professionals do everything from video editing to reference
(playback) on a single monitor.
Dual-link SDI Signal Support
CG232W
Input support includes BNC × 2 (SD-SDI/HD-SDI × 2 or duallink
SDI × 1) for transferring uncompressed video signals, DVI-D,
and D-Sub for direct connection to broad cast and studio sources
as well as desktop PCs. YCbCr 4:2:2, YCbPr 4:2:2, YPbPr 4:4:4
and RGB 4:4:4 SDI signal formats are all supported.

signals, a pseudo-interlace feature minimizes motion artifacts,

that of a CRT.

Preset Color Modes
CG232W
This model offers
preset color modes that
reproduce the color
spaces used in broadcasting
and digital
cinema such as EBU,
SMPTE-C, Rec709 and
DCI almost in their
entirety. To correct color
drift that naturally occurs over time with any LCD monitor, the
bundled ColorNavigator software comes with a reset function for
returning the preset modes to their factory settings.

A range extension feature gives studio professionals the advantage
of using the monitor’s entire 10‐bit grayscale range to see
more detail when doing fine editing work in very dark and very
light tones. Setting the screen to show the entire 10-bit grayscale
range reveals either 6% or 14% more gray tones from 0 (true
black) to 1023 (true white) compared to common broadcast signal
display range capabilities.

3D LUT
CG232W · CG242W
All ColorEdge models incorporate
a look-up table (LUT) for accurate
color and grayscale rendering, but the
ColorEdge CG232W and CG242W
utilize a new EIZO-developed 3D LUT.
While a typical 1D LUT adjusts color
on separate tables for each of red, green,
and blue, a 3D LUT accomplishes this using a single, mixed-color
cubic table. This improves the monitor’s additive color mixture
(combination of RGB), a key factor in its ability to display neutral
gray tones.
Short- and Long-Term Brightness Stabilization
Brightness (cd/m 2 )
CG232W · CG242W · CG301W
Stable brightness is a key factor in
achieving accurate color. However,
fluctuations in backlight brightness
normally occur from startup and can
last for up to two hours. Furthermore,
changes in ambient temperature can
cause brightness levels to fluctuate,
as can the inevitable deterioration of
the backlight’s fluorescent lamp over
time. An EIZO patented backlight sensor detects and counteracts
these influences so brightness is always stable and product life is
extended.

16-Bit Internal Processing
CG232W · CG242W · CG301W
In any color-critical work, the monitor’s ability to produce
black is a great differentiator. With most LCD monitors, the darkest
area of the screen — or black level — is usually too bright.
This leads to banding and washing out of dark grays and dark
colors. With 16-bit internal processing, these ColorEdge monitors
not only come very close to producing a true black, but the
lowest grayscale tones can be distinguished from one another for a
greater level of detail in dark areas.

Brightness and Color Uniformity with DUE
CG232W · CG242W · CG301W
Brightness and chroma uniformity errors are characteristic
of all LCD panels. To counteract this, EIZO has
equipped these ColorEdge monitors with its latest integrated
circuit. This circuit features a Digital Uniformity Equal izer
(DUE) function. DUE compensates brightness and chroma based
on data measured at our factory so that the entire screen will be
almost uniform at each gray level from 0 to 255. A certificate
indicating the unifor mity compensation results is packaged with
each monitor.
Accurate Hardware Calibration
CG232W · CG242W · CG301W
There are two kinds of monitor calibration — software and
hardware. With software calibration, colors are adjusted by
manip ulating the graphics board’s color output, which results in
fewer displayable colors. With hardware calibration, colors are
